I expected to see non-zero value of Reported_Uncorrect/187, but there is no such attribute in the output. Why?

Because WDC decided to omit this attribute. Even if attribute 187 would 
exist, it may mean something different. SMART Attributes are always 
vendor specific.

The "197 Current_Pending_Sector  ... 1" indicates one unreadable sector.

Similar: Because Samsung decided to omit this attribute.
